Understanding Urinary Obstruction in Cats

A urinary obstruction, or 'blocked cat', occurs when a cat cannot urinate, preventing the bladder from emptying. This condition is more common in male cats due to their narrower urethra, which is more susceptible to blockage. Other causes can include urinary tract infections, bladder stones and inflammation (swelling). One common cause is feline idiopathic cystitis (FIC). FIC is an inflammatory condition of the bladder that happens secondary to stress.
